A freak accident while riding a jet ski has sent a vacationer to the intensive care unit.

Levi Dixon was riding on a jet ski over the weekend in Hilton Head, South Carolina, and was knocked off by what witnesses described as a ray, according to WJCL.

Joanna Whipple and boyfriend Thomas McDaniel watched it all happen, WJCL reported.

Whipple said an animal that was “gray on top, white on the bottom with this weird face,” came out and hit Dixon, knocking him off the jet ski.

Whipple said it was about 4 feet in diameter.

McDaniel jumped into the water after the accident to help keep Dixon from drowning. They then got the attention of boaters on a pontoon boat, which then took Dixon to land, WJCL reported.

Dixon suffered broken ribs, a concussion and injuries to his lungs, back and neck, according to his brother. He was ICU at Savannah Memorial Hospital for two days before being released.
